Abstract
L'invention porte sur un procédé pour générer un signal de synchronisation. Le procédé comprend l'utilisation d'un nombre autre que 63 en tant que valeur Nzc dans une séquence Zadoff-Chu utilisée dans la génération d'un signal de synchronisation primaire pour un système de communication sans fil, qui peut être un système LTE 3GPP ou un système LTE-A 3GPP.
